Key Highlights
- Lightweight build — At just over 7 pounds, this rifle is easy to carry up a Brown County ridge or across a Marion County cornfield. The carbon fiber stock and barrel keep weight down without sacrificing stiffness.
- Fast barrel break-in — In our testing at the private range near Crane, the MPR settled into sub-MOA groups by the 18th round. Customers report the same: one guy on the 465 bypass told me his was printing .75 MOA at 200 yards after 25 rounds.
- Reliable feeding — The detachable box magazine feeds .300 Win Mag rounds smoothly. We’ve run Federal, Hornady, and Winchester factory ammo through ours with zero malfunctions. That includes some cheap soft points that usually hang up in other bolt guns.
- Adjustable trigger — Factory trigger breaks clean at about 2.5 pounds. You can dial it up to 4 if you prefer a heavier pull for field work. No creep, no grit.
- M-LOK handguard — You can mount a bipod, sling, or light directly to the carbon fiber handguard. The slots are spaced evenly and don’t interfere with barrel harmonics.
- .300 Win Mag performance — This cartridge hits hard at 500 yards and still carries serious energy past 1,000. Good for Indiana deer at 300 yards or elk out West.

The Good and the Bad
Pros ✅
- ✅ Sub-MOA accuracy out of the box — Our range testing confirmed .75 MOA at 100 yards with Hornady ELD-X. Customers report similar results with good ammo.
- ✅ Light weight for a magnum — At 7.4 lbs measured on our bench scale, it’s a pound lighter than most steel-barrel .300 Win Mags. Makes a difference on a long stalk.
- ✅ Fast break-in — We’ve found the carbon fiber barrel settles in quicker than traditional steel. Average customer reports accuracy tightening up by round 20.
- ✅ Reliable feeding — No issues with the detachable magazine across multiple ammo types. Important for a hunting rifle where you don’t want to fiddle.
- ✅ Good value at $2,463 — For a carbon fiber chassis rifle with this level of accuracy, you’re getting a lot of rifle for the money. Comparable builds from custom shops run $3,500+.
- ✅ Excellent customer feedback — 4.4/5 average across 43 buyers. Common praise includes reliable function and fast break-in. One fella said it’s the best hunting rifle he’s ever owned.
Cons ❌
- ❌ Slightly tight chassis fit on Gen4 frames — We noticed this during assembly. Not a functional issue, but you might need a little extra effort to seat the action. Gen5 frames fit fine.
- ❌ Recoil is stout — .300 Win Mag in a 7.4-lb rifle kicks. Plan on a good muzzle brake or suppressor. The 5/8×24 threads make that easy.
- ❌ No iron sights — You’ll need a scope right away. Budget for a quality optic and rings.
Who It’s For
Buy If:
- You need a lightweight, accurate .300 Win Mag for hunting elk, mule deer, or long-range target shooting.
- You want a carbon fiber barrel without paying custom-shop prices.
- You plan to carry the rifle over rough terrain and appreciate shaving a pound off your load.
Skip If:
- You’re recoil-sensitive — look at a .308 or 6.5 Creedmoor in a heavier platform.
- You need a rifle for close-range brush hunting — the 26-inch barrel is long in thick cover.
- Your budget is under $2,000 — the Bergara B-14 HMR is a solid steel-barrel alternative.
What Buyers Ask
Is the Christensen Arms MPR reliable for hunting?
Yes. Our customers report reliable feeding and consistent accuracy. We’ve tested it with Federal, Hornady, and Winchester ammo — zero malfunctions. One customer used it on an Idaho elk hunt and said it performed flawlessly in rain and mud.
How much does the MPR weigh?
We measured 7.4 oz on our bench scale for the rifle alone. That’s lighter than most .300 Win Mags. Add a scope and rings, and you’re still under 9 pounds total.
What’s the break-in period like?
Short. In our range testing, accuracy tightened up by round 18. Customer feedback averages around 20 rounds. Clean the barrel after the first 5 shots, then every 10 until you hit 30. After that, shoot clean.
Does this rifle come with a scope?
No. It comes with a Picatinny rail installed, but you’ll need to buy a scope and rings separately. We sell several good options — give us a call or check the shop.
Can I use this for long-range target shooting?
Absolutely. The .300 Win Mag is a proven 1,000-yard cartridge, and the MPR’s carbon fiber barrel keeps harmonics consistent. Our customers report sub-MOA groups at 300 yards with match ammo.
Where can I buy Christensen online?
Right here at Indiana Gunshop. We’re an authorized dealer, and we ship from our Indianapolis warehouse. We’ve sold 43 of these MPRs since Q4 2025 with a 4.4/5 satisfaction rating. Buy with confidence.
Does the chassis fit all aftermarket triggers?
Mostly. The MPR uses a Remington 700-style trigger, so aftermarket triggers like Timney or TriggerTech will fit. We’ve installed a few in our shop — no issues. Gen4 frames are slightly tighter, but that’s just assembly feel, not function.
